Power Integrations (San Jose, CA) offers seven new members of its LinkSwitch-PH family of LED driver ICs. Optimized for industrial and commercial settings where high efficiency and system longevity are dominant requirements, the new devices (LNK413-LNK419) are suitable for lighting applications ranging from 3 W bulbs to 55 W replacements for fluorescent lighting fixtures.

Last Thursday, I left New York for DC to check out the World Energy Engineering Congress (WEEC) held at the Washington Convention Center. Though my Amtrak train was a little slow in getting there, the show flew by in a flash.

The U.S. Department of Energy (DOE) has released updated versions of its EnergyPlus simulation software and OpenStudio Plug-in for Google SketchUp, which help engineers and architects design better functioning, more energy-efficient buildings.

Check out the new issue of Lighting Technology for more new feature articles, videos, application stories, tech briefs, products, and more - all on the latest advances in LEDs and solid-state lighting.

Strobe or rotating beacon-type emergency lighting is a requirement on all Minnesota Department of Transportation (Mn/DOT) maintenance and construction vehicles. There is an effort to replace the standard warning lighting with LED-based lights in order to reduce cost of replacement and maintenance.

The heat radiating off roadways has long been a factor in explaining why city temperatures are often considerably warmer than nearby suburban or rural areas. University of Rhode Island researchers are examining methods of harvesting that solar energy to melt ice, power streetlights, illuminate signs, heat buildings, and potentially use it for many other purposes.

University of Michigan scientists have created pixels that will enable LED-projected and -wearable displays to be more energy efficient with more light manipulation possible - all on a display that may eventually be as small as a postage stamp.

Question of the Week

This week's Question: Last week, Elon Musk, chief executive of Tesla, said that the electric car maker would introduce autonomous technology, an autopilot mode, by this summer; the technology will allow drivers to have their vehicles take control...
